The part of the seat you sit on is fine, but the back rest is rather firm to say the least.

I feel a bit sorry for the kids on long journeys so they each get a chance to sit up front for part of the journey with my wife or I sitting at the dinette. We have tried pillows but they distort your seating position.

Does anyone know of a product that might help?

Maybe long term we will get them re upholstered but if there was a quick fix it would be great.

When Richard Tapper came to our van at Malvern to give us a quote he sat down and his first remark was that the foam structure had gone. What we thought was firmness was the seat frame - more especially under the squab rather than the backrest in our case, admittedly.

Both squabs and backrests are far more comfortable now we have had the re-upholstery done.
